Polymerization Method

Polyaniline/Graphene composite (PANIGNS) was synthesized via in situ polymerization method. XRD and SEM results indicated that the polyaniline could uniformly adsorb on the graphene surface and prevent the agglomeration of the graphene sheets. The composite exhibits excellent electrochemical performance. A specific capacitance of 688F/g at current density of 1A/g was achieved in 1M KOH solution. The capacitance retention of 77.3% was acquired after 1000cycles at current density of 10A/g.

Iron oxides are considered promising electrode materials owing to their capability of lithium storage, but their poor conductivity and large volume expansion lead to unsatisfactory cycling stability. In this paper, an inexpensive, highly effective, and facile approach to the synthesis of Fe3O4 nanoparticles/reduced graphene oxide composite (Fe3O4/RGO) is designed. The synthesized Fe3O4/RGO composite exhibits high reversible capability and excellent cyclic capacity as an anode material in lithium-ion batteries (LIBs). A reversible capability of 701.8 mAh/g after 50 cycles at a current density of 200 mA·g−1 can be maintained. The synergetic effect of unique structure and high conductivity RGO promises a well soakage of electrolyte, high structure stability, leading to an excellent electrochemical performance. It is believed that the study will provide a feasible strategy to produce transition metal oxide/carbon composite electrodes with excellent electrochemical performance for LIBs.
